Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The criteria used to detect airway obstruction are either the fixed cut-off points according to GOLD recommendations (FEV1/FVC\<0.70) or the lower limit of normal (FEV1/FVC\<LLN). These indices will be compared to a fixed cut-off FEV1/FEV6 \<0.73 as proposed by Vandevoorde et al. or to a FEV1/FV6 ration \< LLN. Reference equations used are those of Caucasians from the NHANES III survey.
Statistical tests will be done using IBM SPSS 24 software. Cohen's κ will be used to determine if there is an agreement between the definitions of airway obstruction.
